TELEPHONE No. 88 | ||||||||
Known as 'The Corporation Set' (because many were supplied to Municipal owned systems) this is the GPO version of the National Telephone Companies NT 13 model. The telephone was supplied with a magneto bell and generator and was used on C.B.S. and magneto circuits. The GPO model had a wooden top whilst the steel body was printed with a wood grain finish. Whereas the private models had transfers on the front of the case the GPO version had an
instruction notice frame. Early table telephones were connected to the internal wiring with a Strip, Flexible Cord Connection. Click here for more information.
